Small but mighty : Oleic acid functionalized silica particles possess adequate hydrophobicity to stabilize water/oil Pickering high internal phase emulsions. The particles adsorb irreversibly at the aqueous/organic interface and prevent droplet coalescence and phase inversion. Polymerization of the emulsions produced highly porous polymer foams.
